Title: Improvements in methods of and devices for controlling associated machines for opening or cleaning cotton and like fibrous material
IPC: D01G9/22
Filed: 1938-02-21
Abstract: 511,537. Controlling associated machines for opening or cleaning cotton &c. TENNANT, W. J. (Akt.-Ges. J. J. Rieter & Cie.). Feb. 21, 1938, No. 5464. [Class 120 (i)] The feed of material in associated machines such as cleaners and openers is controlled at the various machines, i.e., individually for each machine or commonly for all the machines of a group, by means of corresponding displacements of a gaseous or liquid operating medium in conduits and cylinders containing pistons. In a system comprising a bale opener 1, Fig. 1, having loose and fixed pulleys 3, 4 driven by a belt 6 from the succeeding preliminary opener 2 and controlled by a belt shifter 8, Fig. 4, the raw material is fed through a conduit 13 from the preliminary opener 2 into a hopper feeder 14, Fig. 2, and thence to a scutcher 15. The belt shifter 8 is connected to a rod 9 carrying a piston 10 operating in a cylinder 11 under control of a spring 12 while the scutcher feedroller 16 is driven through a toothed coupling 17, 18, Fig. 3, the part 18 being controlled by a bell-crank lever 19 actuated by a piston 21 and loaded by a spring 22. The cylinders 11, 23 are connected through a pipe line a with a pressure vessel 26 which is charged by a pump 27 with a gaseous medium e.g. compressed air. As shown, the drop lever 30 is raised and the valve 31 is open so that pressure is transmitted to the cylinder 23 and the coupling parts 17, 18 are engaged and the feed roller 16 is driven. The valve 33 controlled by the pivoted member 25 is also open and the belt 6 on the fast pulley 4. When the drop lever 30 falls, the pressure line is closed by the valve 31 and the valve 32 is opened, the spring 22 acting to separate the coupling parts 17, 18 and the spring 12 to shift the belt 6 on to the loose pulley 3. When sufficient material is in the hopper 14 the member 25 is moved to close the valve 33 and open the valve 34 thereby moving the belt 6 on to the loose pulley 3. If the pressure line is of considerable length the member 25 may co-operate with an electric switch 35, 36, 37, Fig. 5. When the member 25 swings back the switch lever 37 is rocked from contact 36 on to contact 35 so that circuit b is closed, the winding 39 is energised and the valve 40 opened while circuit c is opened and the valve 43 is closed thus moving the belt on to the loose pulley.
